Whatever effort you put around the DAC chip, the result is limited by the chip itself and it's ingredients, as there are: a bit of delta sigma and a good portion of oversampling and who knows what else.
To me it is no wonder, the reviewer preferred the AN.
R2R non os with analog filter kicks the modern chip's a**.
Just everything is more expensive as we know...
By the way, in that schematic, do I really see a pair of electrolytic caps back to back, bypassed with a film cap ?
At least this topology will make sure, that you have a lot of "out of band energy" just above 20kHz (22,05kHz). Most amps will not perform perfect under these conditions 🙄
And as said before.... If you like that kind of reproducton, you simply just don't fit into our approach. Just like a Toyota driver will never fall in love with a BMW.
He did not move an inch, except from going upstairs for some Pizza.
But he did mention, that he was deeply impressed by the DALI speakers used in the audition. But somehow he suddently turned 180 degrees...
Guess that's why he is a famous HiFi writer 😉
The most of us was impressed of how much you got out of speakers we consider as crap. Never the less they are not good enough as a reference for testing a Dac . Your resulting sound was not high end. A pity because your superior Gravity amp and Danner Detail are really good.

So your potential customers are stupid because they did not like what you produced 🙄?
Pro sound vs what music lovers (consumers) like is totally different, more often than not, in my opinion. Consumers look for a musical connection with the music that they listen to (people that reported on the sound of your DAC) where as a recording engineer listens for technical perfection, which may times misses the mark, in my experiences. Engineering monitors are not what a typical consumer would consider to be a home audio speaker as they are extremely forward sounding vs audiophile type speakers. Maybe you should start listening to what your potential customer base says that they want from a product, unless you are after the pro sound crowd. 😕
There is a big difference, as the people that have heard it are trying to tell you, but you don't seem to want to hear that. I wish you success in marketing this or any other DAC that you produce

What... you live in Denmark and don't own Dynaudios???? Excuse me.....![]()
Dynaudio are not Danish anymore. I think the owner is from Germany.
Wow! That is sad... no more good Scandanavian heritage any more... Being German should also drive the price way way up. What happened?

@ Mark Allen:
Well... You would be surpriced to know, that stuff made in Denmark normally cost way more than made in Germany. Basically because a Danish worker believes, that he should have about the double payment for his work.
But the Dynaudio factory is still located in Denmark. I live less than 2 miles from it. But even though I know some people there, making it possible to buy a set of speakers at around 75-80% discount, I still choose the DALI speakers.
In my opinion, Dynaudio is world class craftmansship, but very little about musical reproduction.
I did consider buying a set of Dynaudio's, to fit into the Bang&Olufsen stereo I got for my girlfriend 🙂

If you have no analog filter. A common mistake.
Just like a Toyota driver will never fall in love with a BMW.
For a perfect analogy, please have a look at my signature 😛

You did not yet comment on your double electrolytic caps in the signal path.

I really agree. We just do not have the same preference for musical reproduction. That's the great thing about HiFi.
2 completely different sounding DAC's can be equally good, in different ears.
And for people with same preferences as we have, our DAC may very well be one of the best ever made.
But it really takes a good setup to achieve the performance. Use it on a mid end setup, and you will hate.
That's one of the ideas... When going for top performance, in almost any catagory (Including HiFi), everthing has to perform well.
This is the reference setup:
Behringer x-over for top performance....

You had a well respected audio reviewer tell you that the DAC was not all that, and you blow it off as a difference in opinion? There were others there too, but their opinions make no differences. When do you think that maybe the path that you have chosen, is the wrong path for the market that you are trying to reach? Prosound and consumer/audiophile sound are totally different perspective. Again BMW vs Toyota is reversed in my opinion. The prosound people are most like a Toyota (well enginnering and gets us from point at A to B without issue. The audiophile/music lover works on a more emotional level (BMW/Ferrari drivers). Technically perfect, but the thrill of the ride is paramount!
Is your DCX in stock form or has it been moded? Do you feel it is a bottleneck in your system, based on the fact that it is op-amp based?
I have the DCX myself and feels it takes away transparency and musicality, thanks.

That sounds very reasonable, but what does it say about your claim that your DAC is the best in the world?
You had a well respected audio reviewer tell you that the DAC was not all that, and you blow it off as a difference in opinion?
No... The "respected audio reviewer" called it "difference in opinion", or something like that.
He even decided to call the DAC "pretty good", even though it is way out of his preference of sound reproduction.
Guess that's as good, as having a Toyota-lover saying, that a BMW is quite good.

We are not aiming for the pro-sound! That's your misunderstanding.... 🙂 We just choose chip form suppliers recognized by the pro industry. But forget about that. I don't think that I will be able to explain it to you 🙄

That we may have succeded, and that some people have other preferences.
I would call BMW "world class", but still people buy Toyota's 😉
Get the point??
I can explain why I did not say anything at Hurtig and Kurt Von Kubik.
I said quietly that perhaps there was a hole in the middle of the soundstage, then I got a half hours of instruction in microphone technique, and a lot about how much I was wrong.
because the hole in the middle was not!! there.
it was only me there was something wrong with, although I knew the CD very well, and had just heard the CD at Gryphon on their Poseidon system.
After that I should not have said more, perhaps there were other there was a bit reluctant.
Regarding their DAC, it worked immediately smooth and a bit indifferent, and Janils have mentioned it's probably a good average product, but not best in the world, far from it.
Audio Note was in a totally different class, no doubt about it.
But I will make reservations for the assessment of their DAC, because their hifi system was average, and I knew it not. But as I said it was easy to hear that Audi note was in another class. and I also know the Audio Note's DAC from other contexts
I apologize for my English but do not complain to me, complain to google because they are responsible, as I usually do not write English.
I hope you understand it anyway.

Perhaps you should try a first order megalomania-filter. I'm sure it would work wonders for you.
